Song HM, Zink JI.
PMID: 27537252
Phys Chem Chem Phys. 2016 Sep 21;18(35):24460-70. doi: 10.1039/c6cp04843a. Epub 2016 Aug 18.

Creation of structural complexity by simple experimental control will be an attractive approach for the preparation of nanomaterials, as a classical bottom-up method is supplemented by a more efficient and more direct artificial engineering method. In this study, structural...

Simultaneous spectroscopic measurements of the interior temperature and induced cargo release from pore-restricted mesoporous silica nanoparticles.

Nanoscale

Dong J, Zink JI.
PMID: 27150579
Nanoscale. 2016 May 19;8(20):10558-63. doi: 10.1039/c6nr00978f.

Temperature changes initiated within nano structures are being increasingly used to externally activate responsive delivery vehicles. Yet, the precise measurement of the nano environment temperature increase and its correlation with the induced macroscopic cargo release are difficult to achieve....

PMID: 11925166
Inorg Chem. 2002 Apr 08;41(7):1755-60. doi: 10.1021/ic010680m.

The nitridorhenium(V) complexes ReNCl(2)(PCy3)(2) (1), ReNBr(2)(PCy3)(2) (2), ReNCl(2)(PPh3)(2) (3), and ReNBr(2)(PPh3)(2) (4) produce structured emission spectra upon excitation at low temperature. The origin, E(00), occurs at 15 775, 16 375, 15 875, and 16 300 cm(-1), respectively. The vibronic...

Contributions of symmetric and asymmetric normal coordinates to the intervalence electronic absorption and resonance Raman spectra of a strongly coupled p-phenylenediamine radical cation.

Journal of the American Chemical Society

Bailey SE, Zink JI, Nelsen SF.
PMID: 12733934
J Am Chem Soc. 2003 May 14;125(19):5939-47. doi: 10.1021/ja021343v.

Resonance Raman spectroscopy, electronic absorption spectroscopy, and the time-dependent theory of spectroscopy are used to analyze the intervalence electron transfer properties of a strongly delocalized class III molecule, the tetraalkyl-p-phenylene diamine radical cation bis(3-oxo-9-azabicyclo[3.3.1]non-9-yl)benzene ((k33)(2)PD(+)). This molecule is a...

An operational supramolecular nanovalve.

Journal of the American Chemical Society

Hernandez R, Tseng HR, Wong JW, Stoddart JF, Zink JI.
PMID: 15025433
J Am Chem Soc. 2004 Mar 24;126(11):3370-1. doi: 10.1021/ja039424u.

A functioning nanomachine in the form of a supramolecular nanovalve that opens and closes the orifices to molecular-sized pores and releases a small number of molecules on demand is reported. The nanovalve, which is used to open and close...

Resonance Raman de-enhancement caused by excited state mixed valence.

The journal of physical chemistry. A

Wang X, Valverde-Aguilar G, Weaver MN, Nelsen SF, Zink JI.
PMID: 17542568
J Phys Chem A. 2007 Jun 28;111(25):5441-7. doi: 10.1021/jp071203d. Epub 2007 Jun 02.

Resonance Raman and absorption spectra of 9,10-bis(2-tert-butyl-2,3-diazabicyclo[2.2.2]oct-3-yl)-anthracene (2) are measured and analyzed. The contribution of the individual vibrational normal modes to the reorganization energy is investigated. Excited-state mixed valence in this system is analyzed using density functional theory electronic...
